The first symptoms
of
frontotemporal dementia may be personality changes or
unusual behavior. People with this condition may not express any caring for
others, or they may say rude things, expose themselves, or make sexually
explicit comments.

Symptoms of dementia that come on suddenly suggest
vascular dementia or possibly
delirium, which is short-term confusion caused by a new or
worsening illness.

It is important to
know that memory loss can be caused by conditions other than dementia, such as
depression, and that those conditions can be treated. Also, occasional trouble
with memory (such as briefly forgetting someone's name) can be a normal part of
aging. But if you are worried about memory loss or if a loved one has memory
loss that is getting worse, see your doctor.
